If "related" was a typo, it was a happy one. The root problem is that we're getting more and more connected, but those connections have low security. It's too easy for bad stuff to flow across those connections. We're getting related to death.
Much as developers in the past couple of years have really started to grapple with the fact that as wonderful as software libraries are, dependencies have non-zero costs that come with their benefits, connections need to be seen as being having non-zero costs as well. I work in a similar situation myself and I know my philosophy over the past 10 years has very much gone from a permissive "well maybe I'll need this later" open-ended protocol design to a super-strict "this connection moves exactly this set of strongly-typed, verified messages over it and if anybody tries any funny business we slam it shut and scream bloody murder on the monitoring" philosophy. Especially challenging with the Web's support for messaging, which is great for being a web page but is flabby and bloated for a messaging solution, what with all these headers that do magical things in the web servers or anything in between.
As our systems get more and more complicated, biological metaphors seems to be ever more useful, and I think we need to look to nature's highly defensive "programming" a bit more for inspiration. Chemistry has some different characteristics from our programming environment, some to nature's advantage and some to its disadvantage, so we can't blindly copy it, but living things take 'message security' very seriously. You don't last long if you just blindly trust everything out there.
